No ads. No account required. Just focus. FlowStack is a simple productivity timer, task manager, and routine app designed to beat procrastination and sharpen focus by having a clear name and timer for your task. Use it as a flexible timer for personal, work or study tasks, daily routines, or a focus tool if you struggle with multitasking or constant task switching. FlowStack keeps you on track and making real progress, one task at a time. In FlowStack, each task or to-do has an estimated duration and a timer that starts ticking down when you start the session. This makes it easier starting the task, and helps you get into a flow state by focusing on one task at a time. The current task is also shown as a Live Activity and in the Dynamic Island, making it easy to stay on task even while you're using another app. Once you're done, FlowStack pushes you into the next task. Need more time to finish the first task? Simply add more time to the timer, or continue in a flow state where time is unlimited. If you want to use it as a to-do list rather than focus session, you can also complete a task without starting the timer. Perfect for: • Procrastinators who struggle getting started • People with ADHD seeking simple focus tools • Anyone organizing tasks into daily routines • Users wanting a simple system for recurring tasks • Fans of Pomodoro and Atomic Habits (habit stacking, time blocking) • Professionals and students boosting productivity and focus • Anyone starting good habits—fitness, mental health, cleaning, learning, etc. What makes FlowStack different? • Flexible task timer.

About

Parallask

Most planners assume you do one thing at a time. Parallask doesn't. Build your day as a timeline. Tasks have real durations, so they can overlap, sit side by side, or leave deliberate gaps. The shape of the plan is the plan. Drag a bar to move it, drag its edge to make it longer, tap a gap to fill it. Then give it a start time and walk away. At the appointed moment the plan begins on its own, counting down on the Lock Screen and in the Dynamic Island, with the app closed. Each task announces itself as it starts. Nothing needs you to be watching. TIMELINE EDITOR Lay out tasks by dragging. Parallel work sits on its own lane instead of being squeezed into a list. Switch to Task List whenever you'd rather read than drag. RUNS ITSELF Schedule a plan for a time and the days it repeats. Reminders arrive ten minutes before it starts, and the countdown reaches your Lock Screen without you opening anything. A SESSION YOU CAN SEE While a plan runs, the whole timeline plays out with a moving playhead: what's on now, what's next, how long is left. A HISTORY THAT STAYS PUT Finished runs are kept exactly as they ran. Rewrite the plan afterwards, or delete it entirely, and the record of that morning is unchanged. LABELS Five colour-coded labels, named by you and shared across plans, so a glance at the week tells you what kind of day it is. YOUR DAY STAYS YOURS No account. No sign-in. No server, no analytics and no tracking of any kind. Everything you create lives on your device and nowhere else. FREE AND MAX Parallask is free: one plan of your own, the five built-in label colours, and starting sessions whenever you like. Parallask Max adds: - Unlimited plans - The full label colour palette - Scheduling plans to start on their own Max is available as a monthly or annual subscription, or as a one-time lifetime purchase.
